PyQt5 QSpinBox – Getting float point size | pointSizeF() method

  • Last Updated : 22 May, 2020

In this article we will see how we can get the floating point size of the text in spin box. Changing the point size will change the size of the text, pixel and point are two different things some things point can have multiple pixels inside it. It is recommended to change point size for changing the size of the text. Unlike normal point size, floating point size can make the point size in decimal as point size is not a pixel its value can be in float as well there for normal get method will not get the float value as it get only integer value.

In order to do this we use pointSizeF method with the QFont object of the spin box

Syntax : font.pointSizeF()

Argument : It takes no argument

Return : It returns float value



Below is the implementation




# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
  
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
  
        # getting font of the spin box
        font = self.spin.font()
  
        # setting point size F
        font.setPointSizeF(20.25)
  
        # reassigning this font to the spin box
        self.spin.setFont(font)
  
        # creating a label
        label = QLabel(self)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 300, 60)
  
        # getting point size F
        p_size = font.pointSizeF()
  
        # setting text to the label
        label.setText("Floating Point Size : " + str(p_size))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
